There’s a substantial gap between those 16 titles and the next on the list that might qualify. But going on further, here are all the remaining books that more than 1000 people voted for. As it happens, none of their scores were bad–just kind of average–and getting such a wide audience is a kind of notability too:

Finally, the following authors had sequels out that would have put their books higher on my list than Leigh Bardugo’s, if I were counting non-standalone sequels: Brent Weeks, Michael J. Sullivan, Rae Carson, David Wong, Mark Lawrence, Scott Sigler, Cassandra Clare, Max Frei, Catherynne M. Valente, Lois McMaster Bujold, Jim Butcher, and James S. A. Corey. The scores of their earlier works are probably more comparable to the scores of the standalone / series starters above.
